About

I’m a Senior Python Backend Engineer with 9+ years of experience building reliable, production-grade systems using FastAPI and Django. Over the last few years, my work has focused on real-time AI backends, especially Voice AI agents and Computer Vision / Video Analytics — not demos, but systems that run in production with real users, real latency constraints, and real failure handling. What I work on most - Backend APIs: FastAPI / Django, clean architecture, versioning, auth, permissions - Performance & stability: PostgreSQL tuning, Redis caching, rate limits, background jobs - Voice AI systems: real-time STT/TTS pipelines, LLM orchestration, call workflows - Computer Vision systems: RTSP video analytics, YOLO/OpenCV pipelines, alerts & APIs - AI integrations: RAG, vector search, tool calling, automation - Production readiness: logging, retries, Dockerized deployments, clean handoffs Voice AI - Streaming audio via WebSockets - Speech-to-Text (Whisper / Google STT) - Text-to-Speech with interruption handling (barge-in) - Low-latency LLM orchestration - Call automation: support, booking, FAQs Computer Vision - CCTV & RTSP stream processing - Person / fire / fall / intrusion detection - Event timelines & real-time alerts - Edge or on-prem deployments (Jetson, GPUs) Tech Stack Python, FastAPI, Django, PostgreSQL, Redis, Docker AI: LLMs, Whisper, STT/TTS, YOLO, OpenCV, Vector DBs
